A quarter of voters don’t know enough about Menendez to have an opinion, while a majority — 58 percent — say the same about Kyrillos.

“Who is Joe Kyrillos? State Sen. Joseph Kyrillos has a bit of an improvement in name recognition since his debates with Sen. Robert Menendez, but more than half of New Jerseyans still don't know him well enough to decide if they like him or dislike him,” said Maurice Carroll, director of the Quinnipiac University Polling Institute. “Normally, a challenger, even an unknown, can gain a little ground on the incumbent in the final weeks of a campaign. That doesn’t seem to be happening for Kyrillos.”

The poll of 1,319 likely voters was conducted from October 10 through October 14 and has a margin of error of plus or minus 2.7 percentage points.
